Electronic Applications of the Smith Chart: In Waveguide, Circuit, and Component Analysis

The following exercises provide a mini-course in the SMITH CHART, reinforcing the concepts presented in the book with the aid of winSmith. Answers to the problems are provided immediately after each excercise.
The SMITH CHART includes arcs which are incomplete circles that all meet at a point on the far-right of the circumference of the impedance chart.
Questions and Answers to Exercise A
| 1. | Do these arcs represent points of constant resistance or constant reactance? |
|
| 2. | Where are the centers of the circles that define these arcs located? |
|
| 3. | Is the straight horizontal line a member of this family of arcs? What is unique about this line? |
|
| 4. | What impedances are represented by the arcs displayed by winSmith? |
|
| 5. | What can be said about the top half of the SMITH CHART? The bottom half? |
|
Answers
| 1. | Partial circles (arcs) on the impedance SMITH CHART represent points of constant reactance. |
| 2. | The centers of the circles that define these arcs are located on a vertical line which passes through the circumference of the SMITH CHART on the far right. |
| 3. | Yes, the straight horizontal line is a constant reactance arc with an infinite radius with a center at infinity. The reactance of points on this line is zero and it is referred to as the axis of the reals. |
| 4. | The winSmith cursor may be used to determine that the arcs represent normalized impedances (counter-clockwise from the right) of... |
